Like issues raised by eco-warriors showing violent manner possibly (13)

Ross

I believe the answer is:

environmental

Here is my best explanation:

'like issues raised by eco-warriors' is the definition.

'violent manner possibly' is the wordplay.
'possibly' indicates an anagram.
'violent'+'manner'='violentmanner'
'violentmanner' is an anagram of 'ENVIRONMENTAL'.

'showing' is the link.
